If you're running XP, go to Control Panel and open System. In Device Manager, look for a device with a exclamation point or question mark next to it. If you find one and it says "Multimedia Device" or some such next to it, right-click on it and uninstall it, then reboot. Assuming this was some major PC manufacturer (like HP,) on reboot, Windows should find the drivers for it.

It should go black to black, green to green, and orange to orange (the color coordinated pattern). I suspect your problem may be in the audio driver or a bad wire or bad sound card/ports.

First try re-configuring your audio (like you did when the computer was new): If you have an audio card, start the software for that. Start > All Programs > Creative > Creative Sound Console. If you end up in Entertainment mode. Click on the Speakers tab and Autoconfigure the speakers. If you have the on-board audio, see the Realtek audio in the Device Manager. Start > Control Panel > Hardware and Sound > Realtek HD Audio Manager. Click on the Speaker Configuration tab and choose your audio set-up.

Check if the Device Manager has a red x or yellow exclamation point for the audio. Control Panel > Hardware and Sound > Device Manager. Try updating the driver. (In Windows 7, this works best if Windows Updates is set to automatically install drivers as well as other updates. Look in Windows Updates, the driver may be waiting to be installed.) Then try reconfiguring again after a reboot.

Also check if the speakers are getting power. Note: the configuration step above won't work if the speakers aren't powered and plugged in. Try them on another computer if you can.

Hello....No Sound, No Volume Control, Mixer not Found, No Sound device installed…etc etc, This is a generic issue with all Windows OS updates....many of the users are facing this issue....this issue began after an auto update from MS changed many IRQs of Win OS, mainly the Sound and Audio Control system of Windows.1 - R U facing NO Audio / No Sound issue...?2 - Is ur Volume Control not responding ?3 - Is ur Sound and Audio Device in Control Panel Grayed out ?4 - Do u get a msg "No Active Mixer Devices Installed....when u try to open Volume Ctrl etc etc ?

If ur ans to any one of them is Yes...then u are being spammed by Microsoft....as ur Sound Control IRQ is being frozen by a recent update from Microsoft....NOTE..THIS…IS…VERY..IMPORTANT...No file update or any sound driver update can fix it, neither Microsoft is issuing any patch to fix it…or giving any help on this.Full solution is available in my website (Support page)...it's quite simple process to fix it, and I am not charging any money, just trying to do some service and help everyone affected by this stupidity from Microsoft. www.sureshayyar.110mb.comvisit my support page.all the best...

Hi,
The speaker jack is coloured green on newer computers and usually sits alongside a blue and a pink jack. Firstly, make sure your speakers are plugged into the green socket. If this doesn't solve the problem, you need to check in "device manager to make sure your sound card is installed correctly. Make sure the sound card is listed in "device manager" then make sure there is no yellow dot next to your sound card. If there is a yellow dot next to your device, it's a simple matter of downloading the correct driver for the sound card. If you need further assistance regarding this don't hesitate to ask me.
Best wishes,
